The TRETIGHT™ dock seal consists of four main parts:
- Top cushion
- Two side cushions
- Fitting set
The three cushions are separate units that are made in a chloroprene rubber coated synthetic fabric.
The load bearing construction consists of two side brackets, two wall plates and a front plate. This is covered with a corrugated steel roof. The fan is placed under the roof.
The retraction of the top cushion is done by a counter weight and the side cushions are pulled aside by elastic cords.
